Cat Lift Trucks (& Caterpillar) P6000:
Not charging

Mod# 6000
Ser# AT83F00901
machine would not rev up in drive or reverse but will in neutral. Verified a voltage issue with the alternator( bad diodes). Replaced the alternator and have 0 volts at rear of alt output. Thought this would be directly connected to battery positive either direct or through the starter, am I wrong?
I do have batt voltage at the exciter plug on the top of the alt
Am I missing something

You should have B+ at the alternator. I would guess you have a blown fusible link. I think it is around the battery cable fuse box area. It should be a short wire with a connector at each end. I have replaced them on Nissan trucks and they are tied along the harness. I think it should be a 100 amp part number 9130446320. Check with your CAT dealer for the correct part.
